Reath is a late scratch for Thursday's game against the Spurs due to lower back soreness.
This is a tough blow for Portland, as they are again without Deandre Ayton (knee). Reath is coming off the best performance of his career Tuesday, as he erupted for 25 points (9-15 FG, 3-6 3Pt, 4-4 FT), nine rebounds, one block and one steal in 32 minutes. Moses Brown will start at center Thursday and is likely looking at a significant workload.
